THOMAS A. WILLIAMS, OFELKINS, nnwivrnxico.

To all whom it may concern:

Be it known that I, THOMAS A. VVILLIAMs, a citizen of the United States,residing at Elkins, in the county of Chaves, State of New Mexico, haveinvented certain new and useful Improvements in VVell-Drills; and Idohereby declare the following to be a full, clear, and exactdescription of the in- :vention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to a well drill.

An object of the invention resides in the provision of a generallyimproved structure of a machine of this class so that it will be simpleto manufacture and easily operated. V

A further object of the invention resides in so constructing the machinethat it may be conveniently used for spudding in or cutting initiallyinto the ground or for drilling deeply into the ground. 7

With these and other objects in view, such as will appear as mydescription progresses, my invention comprises the combination andarrangement of parts as set forth in and falling within the scope of theappended claim.

In the drawing:

Figure 1 is a side elevation of a machine constructed in accordance withmy invention showing the parts in the positions they will occupy whenthe operation of spudding in or initially "cutting the ground is inprogress:

Fig. 2 is a similar view showing the parts in the positions they willoccupy during the deep drilling operation;

Fig. 3 is a fragmental elevational view showing the positions of theparts when the fly wheel is inoperative to raise the drill;

Fig. 4' is an elevational view looking at right angles to Figs. 1, 2 and3;

Fig. 5 is a sectional view on line 55 of Fig. 2, and

Fig. 6 is a sectional view on line 6-6 of Fig. 2.

The embodiment of the invention illustrated in the drawing includes 'aframe 1 from which a tower 2 extends which is braced by suitablesupports 3. A suitable fly wheel 4 is mounted on the frame 1 in bearings5 and pivotally mounted at '6 on the frame 1 is a rocker member 7 whichincludes a pair of spaced side bars 8 which are secured togetherat th irupper'ends by Specification of LettersPatent. ]Pa fi ng]mtqgfl Well 25,191$ Application filed August 16, 1916.

extending rod 10. A locking member 11 is pivoted tothe frame 1 at 6independently of the rocker member and is connected to the fly wheel 4by a pitman 12. This look ing member 11 is adapted to swing between thebars 8 of the rocker member and to be secured in such position by akeeper 13 which is pivoted at 14 to the bars 8 and is normally drawndownwardly by a spring 15 so that it will engage over the upper end ofthe locking member 11. This upperend is provided with a camface l6 whichwhen the locking member is swung between the bars 8 of the rocker member7 will force the keeper 13 upwardly against the tension of the spring 15and permit the keeper to drop in place over the end of the said look ingmember 11. This keeper may be lifted from its position on the lockingmember 11 by means of a suitable cable 17 which is secured to the keeperand extends over pulleys 18, 19 and 20 and is connected to a controllinglever 21 within easy reach of the operator Thus it will be seen thatwhen the rocker member 7 is locked to the pitman 12 by means of alocking member 11 and the fly wheel 4 rotates, the said rocker memberwill be oscillated on its pivot 6.

When the machine is used for drilling deeply the parts will be in thepositions shown in Fig. 2 of the drawing. At this time a pair oi cables22 is secured, detachably, to the upper ends of the bars 8 of the rockermember 7. These cables pass over a pair of pulleys 23 whichare carriedby the tower 2 and are secured to a temperscrew 24 through the medium ofa cross-head 28. When the fly wheel rotates the rocker memher 7 will beoscillated on its pivot and the temper screw raised and lowered.

When the machine is used for spudding in or initially cutting the groundthe cables 22 are removed from the rocker member and a drill line isarranged in the-manner illustrated in Fig. 1 of the drawing. This drillline is windable upon a drum 25 which is actuated by any suitable meansand passes upwardly overa pulley 26 and thence around a pulley 27 at theupper end of thetower and is attached to the drill. The pulley 26 iscarried by a pair of bars 28 which are slidably mounted on a rectangularrod 29 which rod extends between the upper ends of the side bars 8 ofthe rocker member 7. The pulley may thus have lateral movement in orderthat the cable may be wound evenly f tower and is connected to the slushbucket (not shown) lVhen the locking member ll'is disconnected from therocker member 7 the motion of the flywheel at will be ineffective tooscillate the rocker member and consequently, irrespective of whetherthe operationis that 0f spud ding in or drilling deeply, the

drill will not'be actuated.

- While I have illustrated and described a particular embodiment of myinvention it 7 haS merely been for the sake of convenience and I do notwish to be limitedtothat parr ticular embodiment as it is obvious thatnumerous changes may be made in the details of con'st-ruction withoutdep'art-i'ng from we of this atent m be umai'nea xor the spirit of theinvention or exceeding the scope of the claim.

What I claim is In a well drill, the combination of a frame, a rockermember pivoted to the frame and extending upwardly therefrom andineluding a pair of spaced bars, a locking member pivoted to said frameand adapted to swing between the bars of said rocker member and having acam at its upper end, a keeper pivoted between said bars and adapted toengage over said cam and retain the locking member in cooperativerelation with said rocker member, a spring connected to said keeper andto one of said bars for normally retaining the keeper in operativeposition, a fly wheel, a pitman connecting the locking member and flywheel, and a cable extending from the upper end of the rocker member.

In testimony whereof, I aflix my signature, in the presence of awitness.

THOMAS A. WILLIAMS.
